with all that ive seen and my tiny brain actually comprehend...i hope that all these added abilities...like sprinting and the elusive armour ability perk...that our controls stay pretty close to the same...i kinda like my halo 3 default settings....and for osdt it was cool replacing the x button cause lets face it when ur a marine you cant toss a power drain...will those power ups be present?....also with these huge battles, how will that effect co-op im thinkin LAGtacular!!!!
